In a random test of 128 patients with neoplasms of the stomach and in a control group of 170 persons corresponding to age without any focal lesion at the stomach the connection between carcinoma of the stomach and the chronic gastritis was tested. The carcinoma of the stomach is always accompanied by chronic gastritis. The chronic atrophic gastritis with intestinal metaplasia is significantly more frequent than in control persons. We found the chronic atrophic gastritis with intestinal metaplasia more frequently than in the adenocarcinoma (environmental carcinoma) than in the solid carcinoma. The clear dependence of age of the carcinoma of the stomach is confirmed; particularly great increase of the frequency of the carcinoma in the male in the fourth to the seventh decennium of life, in which case males more frequently have an adenocarcinoma, females, on the other hand, a solid carcinoma.
